Involving older Americans in the war on tobacco. The American Stop Smoking Intervention Study for Cancer Prevention.

The American Stop Smoking Intervention Study for Cancer Prevention (ASSIST) is a collaborative effort of the National Cancer Institute, the American Cancer Society, state health departments, and other public and private organizations to develop comprehensive tobacco use control programs in 17 states. The two main goals of the project are to reduce adult smoking prevalence to 15% or less and to reduce the rates of smoking initiation among adolescents by 50% by the year 2000. There is strong consensus within the tobacco-control field of what needs to be done to accomplish these goals. The key elements of a comprehensive tobacco control effort include (1) an excise tax policy based on raising the real price of tobacco, (2) a ban on all forms of tobacco advertising and promotion, (3) product regulation to reduce the harmful constituents found in tobacco and enforce the use of strong and prominent package warnings, (4) the enactment of policies that protect nonsmokers from inhaling tobacco smoke, (5) comprehensive efforts to eliminate minors' access to tobacco products, (6) ongoing and adequately funded efforts to educate the public about the harmful effects of tobacco, (7) the availability of cessation assistance to persons interested in discontinuing the use of tobacco, and (8) the ending of all financial assistance to the tobacco-growing industry. Because older Americans represent a growing and political influential segment of our society, the enactment of effective tobacco control policies depends in part on generating support for such measures among older citizens. This article outlines several ways in which organizations such as American Association of Retired Persons and the American Cancer Society can work together to advocate meaningful tobacco control policies (e.g., higher excise taxes, clean indoor air laws, etc.).

Nutritional aspects of breast cancer.

Nutrition, in its broadest sense, plays a clear role in breast cancer, identified through its relationship to such known risk factors as rate of growth and development, age at menarche, adult height, postmenopausal body weight, and fat distribution. The relative importance of daily diet is hotly debated. There is no agreement on the relative importance of nutrition's effect, the responsible food groups and nutrients, nor the age or ages at which it can be influential. Evidence linking breast cancer and diet comes from human ecologic and observational studies as well as a body of experimental feeding studies in rats and mice. The population studies, including increasing numbers of migrant studies, and the animal experiments suggest that high-fat diets promote breast cancer, particularly among older women. Studies that compare diets of persons with and without breast cancer and those that record breast cancer incidence among women with different dietary histories have been inconclusive enough as to warrant randomized intervention trials. Recognition of differences between the risk factors for premenopausal and postmenopausal women and increasing insight into the ages at which known risk factors exert their influence have helped in the design of these trials. Human feeding studies and the trials themselves are identifying metabolic changes and their biomarkers as well as biomarkers for changes in fat and nutrient intakes. The Women's Health Initiative Dietary Modification Trial was designed to show whether a sustained (9-year) low-fat, high-fruit-and-vegetable eating pattern will lower the incidence of breast cancer among women who will be between ages 59 and 88 when the trial ends, the time of peak incidence. Meanwhile, the Women's Intervention Nutrition Study will learn in approximately 5 years whether a low-fat, adjuvant eating pattern will improve the prognoses of postmenopausal women with early and moderate stage breast cancer and whether tamoxifen should be used as at least part of their treatment. The results of these trials will have important applications for both public health and the provision of medical care.

Training, role models, and research activity among clinical psychologists.

Compared clinical psychologists (N = 270) with high and low publication rates through questionnaire responses. Highs report dissertation experiences more positively influenced their research motivation. Although the most influential professor in both groups was typically clinical, more highs found the professor emphasized another orientation, particularly empirical research, over clinical expertise. Highs report more time available, collaboration opportunities, and organizational acceptance for their research. Both groups favor empirical methods, although highs and lows agree that a small proportion of psychological research makes a significant contribution. Individual preferences probably interact with situational characteristics, both in training and work settings, to determine research activity.

The Level of Expressed Emotion Scale: a new measure of expressed emotion.

The Level of Expressed Emotion (LEE) scale was developed to provide an index of the perceived emotional climate in a person's influential relationships. Unlike existing measures, the scale was constructed on the basis of a conceptual framework described by expressed emotion theorists. In addition to providing an overall score, the 60-item scale assesses the following four characteristic attitudes or response styles of significant others: Intrusiveness, emotional response, attitude toward illness, and tolerance/expectations. The scale underwent extensive psychometric development procedures: (1) theoretically based item generation; (2) pilot testing with normal and psychiatric populations to select the final items; and (3) construct validation within a schizophrenic population. The results were quite favorable and indicate that the LEE scale has sound psychometric properties of internal consistency; reliability; independence from sex, age, and amount of contacts; and construct validity.

The contributions of self-defeating philosophies, perceived helplessness, and repression to anxiety among psychiatric patients.

Four of the most influential psychological explanations for the development of anxiety attribute it to (1) repressed awareness of undesirable emotions; (2) the emergence of unacceptable feelings from the unconscious; (3) adherence to irrational, self-defeating philosophies; and (4) perceived helplessness/lack of control over one's affairs. To test these theories, the authors administered the Trait Anxiety, Denial, Irrational Beliefs, and Locus of Control scales to 190 psychiatric inpatients. Appropriate zero-order, attenuation-corrected, multiple, and partial correlations were run. Denial was correlated negatively with Trait Anxiety; this is consistent with the view that awareness of unpleasant emotions generates anxiety, but does not support the claim that it is the result of repression. The correlations of Trait Anxiety with the Irrational Beliefs scale were substantial. However, its relationships with Locus of Control were limited and nonsignificant after the effects of the Denial and Irrational Beliefs scales were removed statistically. The findings lend support to the positions that anxiety results from self-defeating philosophies and/or the emergence of unpleasant thoughts about oneself, but give only modest support to the "perceived helplessness" hypothesis and seem to contradict the "excessive repression" explanation.

WISC-R stability and re-evaluation of learning-disabled students.

This study investigated the temporal stability of WISC-R IQ scores for learning-disabled subjects (N = 113). All study subjects were administered the WISC-R for an initial evaluation (M age = 8 years, 3 months) and a follow-up re-evaluation (M age = 11 years, 7 months). Pearson product-moment correlations yielded coefficients that were considerably lower than those previously reported: r = .55, p less than .001 for the Verbal IQs; r = .63, p less than .001 for the Performance IQs; and r = .58, p less than .001 for the Full Scale IQs. Results of t-test analyses indicated that only the Verbal IQ scores were significantly different when the initial evaluation (M = 89.4) was compared to the re-evaluation (M = 85.3), p less than .001. The results suggest that the WISC-R may be less stable for the learning-disabled population than for other groups and that the average 3-year test-retest time lapse was an influential factor in the reduced reliability of this instrument.

Comparisons of two expressed emotion scales with the Camberwell Family Interview.

The relationship of the Camberwell Family Interview (CFI) with two self-report scales purported to measure levels of expressed emotion was assessed. Fifteen schizophrenic patients and 22 of their relatives completed the Level of Expressed Emotion Scale (LEE) and the Influential Relationships Questionnaire (IRQ). The relatives of patients also participated in Camberwell Family Interviews (CFI). Results supported the value of the self-report measures in evaluating the affective environment of patients with schizophrenia.

The acceptability of behavioral and emotional feedback depending upon valence and structure in personal growth groups.

Forty-eight students participated in a one-time personal growth group. Subjects were assigned to one of eight groups. Exercises were conducted to promote interpersonal contact, followed by feedback sessions. Four groups generated and exchanged feedback among group members. Statement lists were used as feedback in remaining groups. Within each set, one group delivered positive-behavioral; one, positive-emotional; one, negative-behavioral; and one, negative-emotional feedback. Positive feedback was more credible, desirable, and influential for recipients and donors; positive-behavioral feedback in particular was more credible. Donors rated unstructured feedback as more credible than structured feedback, with negative-structured feedback the least credible with donors and recipients. Findings are discussed in terms of research and application.

Perceived interpersonal attitudes and psychiatric complaints in patients with essential hypertension.

The association between perceived interpersonal attitudes and psychiatric complaints in a group of hypertensives (N = 37) was evaluated. The Influential Relationships Questionnaire (IRQ), which measures perceived care, overprotection, and criticism, was administered to all patients. Hypertensives with psychiatric complaints (n = 14) were not different in terms of age, gender, obesity, smoking, alcohol intake, occupational stress, drug treatment, and baseline systolic and diastolic blood pressures compared to hypertensives without psychiatric complaints. They were, however, different in perceiving their social environment. Hypertensives with psychiatric complaints perceived their social environment as less caring, more overprotective, and more critical. Finally, patients without psychiatric complaints showed better outcome in terms of baseline vs. follow-up measures of systolic and diastolic blood pressures than did patients without psychiatric complaints.

Community leaders' attitudes toward family planning.

Four separate samples of lawyers, businessmen, ministers, and physicians were requested to complete four separate non-overlapping attitude questionnaires in an effort to assess their attitudes toward sterilization, individual responsibility for contraception, family size, social responsibility, overpopulation, and contraception in the lower class. The data indicated that the four professional groups differed in their attitudes and those differences provided the impetus for suggestions focused on developing and maintaining a positive relationship between the influential members of the community and the family planning clinic.

Toward the explication of the value contexts of the community psychologies.

Value issues are inseparable from any scientific pursuit and they become particularly influential in the applied scientific areas of community and behavioral community psychology. The explication of value positions is one way of dealing positively with the ubiquity of value issues. The role of values in community mental health, community psychology, and behavioral community psychology are contrasted. Implicit value positions are entrenched in the terminology of community psychology and community mental health theory while theory in behavioral community psychology, because of its functional rather than structural orientation, does not contain the same level of value positions. Traditionally, value positions have been concerned with the quality of life, i.e., what makes up the "good life." However, the worldwide crises of starvation, nuclear armament, and pollution necessitates an orientation to a more fundamental type of value, i.e., survival of the species or the opportunity for life. Through the explication of quality-of-life values, the public and psychologists designing community helping programs can evaluate the compatibility of quality-of-life and opportunity-for-life values.

Reflections on the golden age of Columbia psychology.

This paper discusses the Golden Age (1920-1940) of the Columbia University psychology department and analyzes some of the sources of its strengths and weaknesses. Much of the credit goes to Robert S. Woodworth, the dean of American experimental psychology, who set up the objective eclectic orientation of the department, recruited a remarkable group of competent faculty members, and above all kept up a cooperative unified spirit in the department. Because the Columbia University psychology department was so influential during its Golden Age, its organization, staffing and departmental characteristics are analyzed. Probably the key to its success was the capability of a guiding genius, Robert S. Woodworth, who gathered a remarkable group of scholars about him. Woodworth's objective eclectic orientation provided the broadest possible approach within a rigorous experimental-statistical orientation. Woodworth's scholarly approach pervaded the department so that many of his colleagues also wrote pioneering encyclopedic works in their particular fields of specialization. The writings of the Columbia psychologists truly shaped the field.

David Hartley's Newtonian neuropsychology.

David Hartley's association psychology has been immensely influential. His vibrationist neurophysiology has, in contrast, been largely overlooked and forgotten. Hartley's vibration theory is examined. On the one hand it is shown how closely it is related to Sir Isaac Newton's mathematical physics and on the other how well it complements the association theory. The vibration theory, indeed, strongly influenced Hartley's associationist psychology and hence is of more than merely antiquarian interest. Although Hartley's understanding of the central nervous system has long been superseded, his general ideas prefigure some aspects of contemporary neurophysiology and philosophy of mind and thus provide a further reason for rescuing his vibrationism from oblivion.

Educated insane: a nineteenth-century psychiatric paradigm.

In the 1830s the time-honored notion that excess study could lead to madness underwent a significant change in America. Under the influence of Enlightenment pedagogy and phrenology, influential superintendents like Amariah Brigham and Isaac Ray feared that the "unnatural" overstimulation of children in schools would ruin their development. In the second half of the nineteenth century, as belief in environmental determinism waned and assumptions about what is "natural" changed, this psychiatric etiology was debated; then, overthrown. By the turn of the century, education was thought to aid, not harm, the mentally ill.

Psychology and homosexuality: the British Sexological Society.

The British Sexological Society was a largely unknown society composed of influential people of the early twentieth century in Great Britain. The present research is an archival study of the Society and its work concerning homosexuality. Issues addressed by the British Sexological Society are relevant to the early development of sexual emancipation movements as well as to issues of sexuality today.

IL-10 deficiency prevents IL-5 overproduction and eosinophilic inflammation in a murine model of asthma-like reaction.

Eosinophilic inflammation and bronchial mucus secretion are among the characteristic pathological changes in asthmatic reaction, which is mediated by Th2 type responses. Although it belongs to Th2 cytokines especially in the mouse, IL-10 is often considered an inhibitory cytokine for both Th1 and Th2 cells. In the present study, using a murine asthma model induced by ovalbumin (OVA), we demonstrated that endogenous IL-10 is critical for the development of asthma-like responses. Specifically, in comparison with wild-type controls, IL-10 gene knockout (KO) mice showed significantly reduced IL-5 production, eosinophilic inflammation and mucus production without notable changes in IL-4 and IgE responses following i. p. sensitization and subsequent intranasal challenge with OVA. In addition, Th1-related cytokine (IFN-gamma and IL-12) production in IL-10 KO mice was significantly higher than that in wild-type mice. The results suggest that endogenous IL-10 plays an important role in promoting pulmonary eosinophilic inflammatory reaction and mucus production during asthmatic reaction. The data also argue that IL-10 may be more influential in the development of IL-5-producing Th2 cells which differ from typical Th2 cells producing both IL-4 and IL-5.

Intrusiveness of rheumatoid arthritis on sexuality in male and female patients living with a spouse.

OBJECTIVE: To determine whether physical disability, pain, depressive mood, and criticism by the spouse are differentially related to intrusiveness of rheumatoid arthritis (RA) on sexuality in male and female patients. METHODS: Physical and psychological aspects of health were assessed in 102 male and 118 female RA patients who were living with a spouse. Patients were classified into 3 levels of intrusiveness of RA on sexuality. The data were analyzed by means of analysis of covariance and multiple regression analysis. RESULTS: Greater intrusiveness of RA on sexuality was related to greater physical disability, pain, and depression in male and female RA patients. Female patients, compared with male patients, appeared to have lower levels of mobility and self-care. Male and female patients did not differ in their level of intrusiveness of RA on sexuality. CONCLUSION: Physical disability, pain, and, to a lesser extent, depression were found to contribute to intrusiveness of RA on sexuality. It is suggested that differences in sexual motivation between men and women might have been influential in the absence of gender differences in intrusiveness.

Granular Hydrogels as Brittle Yield Stress Fluids.

While granular hydrogels are increasingly used in biomedical applications, methods to capture their rheological behavior generally consider shear-thinning and self-healing properties or produce ensemble metrics (e.g., dynamic moduli) while neglecting transient yielding and unyielding processes. Combining oscillatory shear testing with Brittility (Bt) via the Kamani-Donley-Rogers (KDR) model, this work shows that granular hydrogels behave as brittle yield stress fluids. This work quantifies steady and transient rheology as a function of microgel properties and granular composition for polyethylene glycol and gelatin microgels. The KDR model with Bt captures granular hydrogel behavior for a wide range of design parameters, reducing the complex rheology to a determination of model parameters. In granular mixtures, this work observes monotonic dependencies of the elastic modulus, structural viscosity, and brittility upon granular composition, while the yield stress is lower for mixtures. Microgel size distribution and polymer fraction are the most influential parameters in monolithic granular hydrogels, while microgel size and packing density are less impactful. The model robustly captures self-healing behavior and reveals that granular hydrogel relaxation accelerates with an increased small-amplitude strain rate. This quantitative framework is an important step toward rational design of granular hydrogels for applications ranging from injection and in situ stabilization to 3D bioprinting.
